3 C aims. .1

My invention relates to a tobacco pipe, and it has for one of its objects the provision of a sec tional pipe embodying in its construction distillate-traps readily accessible upon sepa ation of the sections so as to. enable the pipe to be easily cleaned.

Another object of my invention to provide. a tobacco pipe which need not materially deviate from the formation or design of the usual tobacco pipe, but which has the usual upwardly-opening bowl with its laterally extending shank and a nc)uth.-pi.ece connected by an intermedia e. mem ber constructed to contain dis illateetraps. or

m particularly a distill.ateetran and a sumo or precipitating chamber into which the oils, or condensates created by the burning of the t bacco Will be collected so that comparatively dry smoke issues from the mouth-piece.

It is well known that with many smokers using tobacco pipes, saliva finds its way through the mouth-piece, into the shank or other existin ortions of a. pipe between the mouthpiece and the tobacco bowl; and it is another object of my invention to provide a tobacco pipe in which the saliva, in addition to the condensates or distil lates released or produced by the burning of the tobacco, will be collected in the sump or precipit in chamber, the cond nsation. or distillate being partly filtered out and absorbed within a trap before the smoke rea h s th sump or precipitating chamber, and further wherein the pipe is so constructed that the condensates or distillates and the saliva can be easily removed and the pipe thoroughly cleaned.

A further object of my invention is to provide a pipe of the kind described in which, the smoke from the burning tobacco is caused to travel through a. circuitous course or passage. in which is included a trap provided with absorbent material and a sump or precipita ng chamber and hrou h both of which the. smoke from the burn. ing tobacco is caused to travel and pass bey nd in a condition freed of. moisture so t t Whe reaches the tip of the mouth-piece, it will issue fr m n a drycondition With the above and other objects in view to be hereinafter described, the accompanying drawings illustrate one embodiment of the invention as set out in the appended claims,

In the drawings-- Fig. l is a side elevation of a tobacco pipe constructed as in accordance with my nventi n.

Fig. 2 is an enlarged longitudinal section taken from the opposing ends of the mouth-piece and shank of the tobacco bowl and the intermediate member connecting the. shank with the mouthpiece.

Fig. 3 is a detached perspective view of the intermediate member of the pipe, or more particularly, the stem of the pipe.

Fig. 4 is a side elevation of one of the two sections of the intermediate member, showing the inlet or inner end face of the same inclined to the axis thereof.

Fig. 5 is a, transverse section taken on line 5-5, Fig. 2., looking in the. direction oi the arrow crossing said line.

Fig- 6 is a transverse section taken on line 6..6, Fig. 2, looking in the direction of the arrow crossing said line.

The pipe comprises the usual tobacco bowl I, in which the tobacco to be burned is placed, and extending from said bowl is the usual shank 8 having a longitudinal bore 9 therein connected with the interior of the bowl 1 by a smo e Dassa e ID in the usual manner. ll designates the mouthpiece, between which and, the shank 8 a moisture-absorbing and. collecting member I2 is interposed. This member preferably comprises three sections, l3, l4 and I5 connected together in any approved manner so that in effect a unitary structure is provided.

The section l3 of the moisture-absorbing and collecting member has a cylindrical body portion 15, hollowed out from Opposite ends, as at H, l 8, to receive portions of the sections I4 and i5, respectively, and to provide a solid intervening portion i9 separating the hollowed-out portions l! and H3. The hollowed-out portion 11 is internally screw threaded from its outer end inwardly, a at 2i). and threaded into the so threaded portion is the section 15 which is in. the form of a plug 21 having a, reduced outer end 2.2.. adapted to be slipped into the longitudinal bore 9 in the shank t of the tobacco bowl 1, and passing longitudinally and preferably axially h u this plug is, a smoke passage 23, The. plug also h axial nubs 24, 24 projecting from opposite end. faces. through. which said smoke pas ag 23 is continued, said. hubs being separated by annular spaces from the walls of the parts into which they project so as to minimize entrance of sedimental distillates and other moisture into the mok passage. When the plus is threaded into the body portion 16 of the intermediate member. the hub 24 is spaced a distance from the solid portion ii in said memb r and the pace. so formed serves as a smoke chamber 25 into which cotton-batting or other absorbent material 25 is Placed, while the nub. 24 extends into the bore 9.

It is, of course, to be understood that the plug 2| may be fastened into the body portion l6 of the intermediate member by means other than the screw-threads described and the reduced outer end 22 of said plug need not necessarily be slipjointed into the shank of the .bowl, since this connection may be screw-threaded in the manner resorted to in many tobacco pipes for connecting the mouth-piece directly with the shank of the tobacco-bowl member.

Depending from the cylindrical body portion l6 of the intermediate member is a cylindrical projection 21 which is bored out from its lower end, as at 28, and formed in the solid portion i9 is a smoke passage 29 which leads downwardly into the depending portion 2'! and is enlarged therein, as at 30, to form a downwardly facing annular shoulder 3|. The upper end of the smoke passage 29 is connected by a port 32 with the upper end or top of the smoke chamber 25 and therefore said port may be considered as forming part of said smoke passage connecting said boredout portion 28 with said smoke chamber. By opening the smoke passage 29 into the upper end of the smoke chamber, moisture from the absorbent material 26 in the smoke chamber, even if saturated, cannot freely enter the passage 29. The bored-out portion 28 serves as a sump or precipitating chamber, as will be more particularly set out hereinafter.

From the sump or precipitating chamber 28 a smoke passage 33 extends upwardly into the hollowed-out portion I8 of the intermediate member, and entering said hollowed-out portion is the reduced inner end 34 of the section I4 of said intermediate member. Section M has a bore formed lengthwise therethrough which trends at an angle to the axis thereof so that when the section I4 is properly connected to section l3, the bore 35 is inclined upwardly and outwardly and it is to receive the usual reduced end of the mouth-piece l l, as clearly shown in Fig. 2 of the drawings. It is to be noted that the end face of the reduced inner portion 34 of section [4 is disposed at a slightly acute angle to the axis of the bore in said section and that the entrance to said bore at its inner end has what may be termed an overhanging wall, or otherwise expressed, a gradually receding wall toward the bottom of the bore and that the point of greatest recession of said bore forms an angle with the upper end of the smoke passage 33.

The exterior of the cylindrical projection 21 is screw threaded and receives a cap 36 to close the inwardly bored-out portion 28 of said projection, thus serving as a removable bottom for the sump orpreoipitating chamber formed in said projection. Cotton-batting or other absorbent material 31 is placed inthe sump or chamber 28, for a purpose to appear hereinafter.

A pipe constructed as described, therefore, has a draft passage from its tobacco bowl I to the extreme outer end of the mouth-piece H so that smoke from the burning tobacco will pass freely therethrough, due to the provision made for collecting sediment, precipitate, or condensates without obstructing the smoke passage through the stem of the pipe, which may be considered as comprising the shank 8, the moisture absorbing and collecting or intermediate member 12 and the mouth-piece, even though the smoke passage through portions of the stem are circuitous and trend in reverse directions along part of said passage.

When' drawing upon the pipe, smoke from the tobacco bowl enters the bore 3 through the smoke passage [0 and continues from the bore 9 through the smoke passage 23 in plug 2|, thus entering the smoke chamber 25 and in the latter passes through the absorbent material 26 so as to filter out of the smoke at least some of the distillates or condensates that may have been produced between this point and the tobacco bowl. Most of the distillates or condensates produced between the bowl I and the plug 22 are trapped in the bowl 9 by the nub 24 since any condensates accumulated in the bore could not well be drawn over the nub 24 and into the passage 23 when drawing upon the pipe. The smoke continues in its course downwardly through the passage 29, after having filtered out some of the oils or distillates, and enters the sump or precipitating chamber 28 where it collects and is absorbed by the absorbent material 31 therein. The smoke then reverses its course by passing upwardly through the passage 33 and entering the bore 35 of the section I4 and from the bore 35 it escapes through the smoke passage in the mouth-piece ll, reaching the mouth of the smoker in comparatively cool and dry condition.

After smoking for a considerable length of time without renewing the absorbent material in the stem of the pipe and without cleaning the passages thereof, the oils and condensates of the burning tobacco build up on the walls of the chambers and of the passages and by reason of the use of the nub 24, such moisture and condensate cannot reverse their course by passing through the smoke passage 23 and lodging in the bore 9 of the shank 8. Thus a comparatively clean smoke passage is assured from the bottom of the tobacco bowl to the smoke chamber 25 and any precipitate not absorbed by the absorbent material 26 will, therefore, gravitate to the bottom of said smoke chamber.

The smoke cleared of most of the oils, distillates or condensates released or produced by the burning of the tobacco and drawn into the smoke chamber 25 continues on its course through the passage 29 and enters the sump or precipitating chamber 28. Any remaining oils, distillates or condensates adhering to the walls of said passage eventually find their way into the sump or precipitating chamber 28 by flowing downwardly under gravity, thus preventing clogging of the passage. The accumulation of oils, distillates or condensates in the sump is prevented from passing through the passage 29 in a reverse manner by the annular shoulder 3| formed in said passage.

Some smokers have a habit of releasing saliya while smoking and this mixes with the smoke passing through the SmOke passage in the mouth piece. Thus in some instances the smoke becomes moistened before reaching the mouth of the smoker even though it enters the passage in the mouth-piece in a dry condition. For this reason, any moisture passing from the mouth of the smoker into the stem of the pipe will eventually reach the bore 35 in the section M and be delivered through the smoke passage 33 to the sump or precipitating chamber 28.

In the event that the accumulation of oils, distillates or condensates accumulated in the sump 28 becomes excessive, the draft created through the stem of the pipe in the direction toward the mouth of the smoker may carry up some of the oils, distillates or condensates to mix with the saliva and smoke and by reason of the fact that the bore 35 has its lower entrance portion receding, a freer escape of the moisture from the section M takes place and assurance of such moisture being disposed in the sump is had under all conditions.

A pipe smoker smoking a pipe constructed according to this invention having trained himself not to release saliva in the mouth-piece of the pipe, will be assured a dry and cool smoke, since the course of the oils, distillates or condensates in a manner reverse to that created by drawing upon the'pipe is prevented by use of the nub 24 on the plug 2| and the annular shoulder'3l formed in the smoke passage 29 and, therefore, accumulations of such undesirable constituents of the smoke cannot lodge in quantities along the circuitous smoke passage to contaminate the already moisture laden smoke, or the smoke after being freed of the undesirable moistures.

Having thus described my invention, what I claim is:

A tobacco pipe, comprising a tobacco bowl having a shank projecting therefrom, a mouthpiece and a member interposed between said shank and said mouth-piece, said interposed member being bored out from opposite ends to form a solid portion between said bored-out portions and to receive the mouth-piece at one end thereof, a plug removably applied in the other end thereof and spaced from said solid portion to form a smoke chamber, said member having a downwardly projecting portion bored out from its lower end upwardlyand having a cap applied to its lower end to form a sump, a smoke passage connecting said sump with said mouthpiece, and a smoke passage through said solid portion connecting the top of said smoke chamber with said sump, absorbent material within said smoke chamber closing one end of said lastmentioned smoke passage, and absorbent material in said sump at the other end of said lastmentioned smoke passage.

2. A tobacco bowl having a shank projecting therefrom, a mouth-piece provided with a smoke passage and a removable intermediate member comprising two sections; one section having a hollow cylindrical body provided with a solid portion between its ends and a depending cylindrical projection hollowed out from its bottom upwardly, a plug inserted into said cylindrical body portion at one end thereof and having means of connection with said shank, said plug having a smoke passage therethrough and being spaced from said solid portion to form a smoke chamber between the two, a cap removably closing the bored out lower end of said depending cylindrical projection to form a sump, a smoke passage through said solid portion connecting said smoke chamber with said sump, and the other section having means to receive the adjacent end of the mouth-piece and means to receive the other end of said cylindrical body portion, said other section having a downwardly and outwardly inclined inner end face, a smoke passage between the said sump and said other section, and filtering material in said smoke chamber and absorbent material in said sump.

3. A tobacco pipe, comprising a tobacco bowl having a shank extending therefrom, said shank having a smoke passage leading from said bowl to the outer end of said shank, a mouth-piece having a smoke passage therethrough, and an intermediate member detachably applied to the outer end of said shank and adapted to have said mouth-piece detachably applied thereto, said intermediate member comprising two sections, one of which has a circuitous passage therethrough, a smoke chamber provided with a filtering material, and a sump provided with absorbent material, the other section being removably applied to said first-mentioned section and having a bore therein at an angle to the longitudinal axes of said shank and the first-mentioned section of said intermediate member, said mouth-piece having means to removably apply the same to said second-mentioned section so as to maintain the smoke passage therein in axial alinement with the bore of said section and thus incline that i portion of the smoke passage extending from the free end of said mouth-piece to said sump, when the pipe is held in the mouth, in a downward direction so that any moisture accumulating along such parts will enter the sump to be absorbed by the absorbent material therein.
